Northern blot analysis of

FIG1 expression in PMBL versus NM-DLBL. Total RNA (5 μg) extracted from the 5 original PMBLs and the 5 original NM-DLBLs used to generate RDA representations was loaded on each lane. Ethidium bromide–stained 28S and 18S rRNA bands are shown for comparison (top). Hybond N+ membrane was hybridized with the α-³²P–labeled human FIG1 RDA fragment.
